I want to present my new blog devoted to Mechanical Engineers, who perform their professional duties in the different parts of the World Ocean despite the difficult working conditions. The primary purpose of this blog is to help them in their daily hard work. Author hopes that the technical documentation, articles and notes, which are posted on this blog, will be interesting for both experienced professionals and novice mechanicians, which are just beginning their careers. Also I think that this blog will be useful for all mechanicians because many of the described machines and mechanisms are widely used ashore.
